Storyline freezes on specific words

Hey everyone,

for some time my Storyline freezes on various words, if they are present on the current slide.
It becomes unresponsive for minutes, then I can shortly interact (I'm using this to escape to another slide), this ramps up my fans to 100%, it stretches the window to overlay my taskbar und sometimes the screen goes black (except for the edges).

My workaround is to add spaces in those words, but I'm at a point where I cant do that anymore, the list of words keeps growing and it takes so much time. 

I've had that on Windows 10 and now on Windows 11, over the years I've tried Storyline 360 Updates 56, 69, 78, 90, 97 and currently 102 and the have all done that.

It happens with every font I've tried and even in empty projects. And it does not matter whether I type or paste them, but sometimes it does make a difference if they all all caps or not. I have always suspected the spell checking, but I have no further clues. Also URLs do the same thing often, as soon as they are recognized as an URL, so I add spaces there as well.

Some examples of words, that freeze for me:

COMPETEN-CIES
CONCLU-SION
FOUN-DATION
APPRECIA-TION
sta-tistics
super-visors
responsi-bility
yea-rs
sus-tainable
s-trategy
f-inancing
deve-lopment
dif-ference
con-ceptual

I know this seems to be a specific problem to my machine, but maybe someone sees a pattern here or has had this before, as I could not find similar cases via searching.

Thank you
